problem with init-udev on startup

[slgtheindividual]

Ok so when I start up ubuntu now I get an error message which says something like

"scripts/init-udev/line 21/ nuke not found"

(I'm not sure exactly as it only shows up briefly) also after logging in I get a blank black screen for quite a while before it shows me my desktop.

I get the feeling this is all related to a (now fixed) problem I was having

http://ubuntuforums.org/showthread.php?t=2187724

any help would be greatly appreciated.

actually I made a mistake, it says "scripts/init-bottom/udev/line 21/ nuke not found"

slgtheindividual; Hello, once more .

Let's see if this is the control file in question, and if there is a problem with it:

cat -n /usr/share/initramfs-tools/scripts/init-bottom/udev

strange things do happen

slgtheindividual' Welp,

Looks like someone has been editing system files !
Line 21 does not look like anything I have ever seen before.

Did you make a backup of the file prior to editing ?
NO ??
Remind me once more what version you have installed:

lsb_release -a
uname -a

Version 13.04 looks like this:

sysop@1304mini:~$ cat -n /usr/share/initramfs-tools/scripts/init-bottom/udev
1 #!/bin/sh -e
2 # initramfs init-bottom script for udev
3
4 PREREQ=""
5
6 # Output pre-requisites
7 prereqs()
8 {
9 echo "$PREREQ"
10 }
11
12 case "$1" in
13 prereqs)
14 prereqs
15 exit 0
16 ;;
17 esac
18
19
20 # Stop udevd, we'll miss a few events while we run init, but we catch up
21 udevadm control --timeout=121 --exit || \
22 echo "udev exit failed -- rc=$?"
23
24 # Move /dev to the real filesystem
25 mount -n -o move /dev ${rootmnt}/dev
sysop@1304mini:~$

Looks like we are hitting close to home !

got it by the tail

I'm not saying you're wrong, but I never edited that file (I tend not to mess with stuff when I don't know what it does lol) so I have no idea what happened.

Anyway here's the output:

~$ lsb_release -a

slgtheindividual; Hey !

Strange things happen !

Lemme have a bit to get caught up on the forum and I will (RE-)boot into my 13.10 install and see what that files looks like there.
(need to do the updates on that install, anyway)

I'll Be Bacckk

[Bashing-om]

slgtheindividual; I am back.

Now a bit of uncertaintly do exist:
Here is my 13.10 "udev" file:

sysop@1304mini:~$ cat -n /mnt/backup/udev-1310
     1  #!/bin/sh -e
     2
     3  PREREQS=""
     4
     5  prereqs() { echo "$PREREQS"; }
     6
     7  case "$1" in
     8      prereqs)
     9      prereqs
    10      exit 0
    11      ;;
    12  esac
    13
    14  # we cannot properly synthesize LVM LV change events with udevadm trigger, so
    15  # if we use LVM, we need to let it finish; otherwise we get missing LV symlinks
    16  # (LP #1185394)
    17  if [ -x /sbin/vgchange ]; then
    18      udevadm settle --timeout=121 || true
    19  fi
    20
    21  # Stop udevd, we'll miss a few events while we run init, but we catch up
    22  udevadm control --timeout=121 --exit || \
    23              echo "udev exit failed -- rc=$?"
    24
    25  # move the /dev tmpfs to the rootfs
    26  mount -n -o move /dev ${rootmnt}/dev
    27
    28  # create a temporary symlink to the final /dev for other initramfs scripts
    29  rm -rf /dev
    30  ln -s ${rootmnt}${udev_root} /dev
    31
sysop@1304mini:~$

And too confuse matters more: this is 12.04's ;

sysop@1304mini:~$ cat -n /mnt/backup/udev-1204
     1  #!/bin/sh -e
     2  # initramfs init-bottom script for udev
     3
     4  PREREQ=""
     5
     6  # Output pre-requisites
     7  prereqs()
     8  {
     9          echo "$PREREQ"
    10  }
    11
    12  case "$1" in
    13      prereqs)
    14          prereqs
    15          exit 0
    16          ;;
    17  esac
    18
    19
    20  # Stop udevd, we'll miss a few events while we run init, but we catch up
    21  udevadm control --timeout=121 --exit || \
    22          echo "udev exit failed -- rc=$?"
    23
    24  # Move /dev to the real filesystem
    25  mount -n -o move /dev ${rootmnt}/dev
sysop@1304mini:~$

-------------
Let's do this .. pending advisement from those of greater knowledge:
make a back up of the current "udev" file:

sudo cp /usr/share/initramfs-tools/scripts/init-bottom/udev /usr/share/initramfs-tools/scripts/init-bottom/udev-old

Now let's edit the file;
make line 21 and 22 like so:

 rm -rf /dev
 ln -s ${rootmnt}${udev_root} /dev

in the favorite text editor "gedit"; in accord with what my 13.10 install has.

gksudo gedit /usr/share/initramfs-tools/scripts/init-bottom/udev

save the file, exit back to terminal, reboot and see what happends.

OK, all looking good, now let's see what the package manager says:

sudo apt-get update
sudo apt-get upgrade

AND post back IF there are errors in the package management system. Still looking good ?
Once more (RE-)Boot, and tell me all is "finer than a frogs hair" !

that's what I think

[slgtheindividual]

ok after editing the file I'm still getting the exact same error at startup and black screen.

also I tried to run an update after restarting but it stops at
